The United Kingdom has detained the first group of migrants arriving on small boats under a new bilateral agreement with France known as the 'one in, one out' deal. This treaty allows the UK to return undocumented migrants who cross the English Channel to France. British Interior Minister Yvette Cooper confirmed these initial detentions, marking the first enforcement of the deal. The detained migrants could be sent back to France within weeks. The agreement aims to regulate and reduce irregular Channel crossings, which have surged to over 50,000 since Labour leader Keir Starmer took office, representing a nearly 50% increase compared to the previous year. In addition, the UK Home Office has expanded its 'deport now, appeal later' scheme, adding 15 new countries to expedite the deportation of foreign criminals before their appeals are heard. This policy affects criminals from over 20 countries, allowing the government to deport individuals immediately after their first-instance convictions. These measures reflect the UK government's intensified efforts to manage migration and criminal deportations amid rising Channel crossings and related challenges.
